nnnnnrmrznm Specification of Letters Patent.

Application tiled March 7, 1914;. Serial-No. 828,135.

T0 all Awhom it may concern v Be it known that I, 'GLnN'OBmsN, a citizen of the United States, and a resident of Manhattan, State of Kansas, have invented certain new and useful Improvements in Dehumidi'zersof which the. following is a full and exact specification.

This invention relates to dehumidizers and has for its principal object to provide a device of this character which is of simple and inexpensive construction easily maintained, and effective at all times not only to preserve the air of a room at a suitably dry and low temperature but which also puriies the air within a room despite the exhalations of the occupants thereof.

Other objects will appear as the invention is more fully described and explained in the following'specification, illustrated in the ac- 4 companying drawings and pointed out in the appended claim. 4 Y

In the drawings, Figure 1 is a longitudinal sectional view of my device. Fig. 2 is an end elevation of the same, with parts broken away and other parts'lin section. Fig. 3 is a face view of the screen and its frame. Fig. v4 is an' enlarged'detailragmentary view of one of the pipes. Figa 5 is a similar sectional view showing a modified form of the arrangement of pipes within the casing.

Referring now more mirticularlyA to the drawings, reference numeral 1 designates a container which, in this instance,'is in-the form of a! hollow lcylinder and through' the -upper surface 'of which are apertures 2,

which communicate with a 'chamber 'whose outlines are marked by the top surface '4 and end and side walls 5 and 5", respectively, the said walls being secured to the saldcontainerlby any suitable means such as .machin screws indicated at 6, and at one end ofthe said chamber is a pipe 7 'which is adapted to communicate with any Suitable source of water supply. The forward end of the said container may be supof pipes, indicated at 15, and around each end of each of which is a bead 17 the function of which is to hold each of the said pipes in spaced relation to its adjacent pipes. Within the left-hand end, (see Fig. 1) of the said container is a' fan 18 whose spindle 20 theradially projecting arms 20a of which are secured `at 21 to the interior of the said container. Y

22 indicates .a motor upon whose central shaft is alixed a pulley 23 which is connected by means of a belt 23 to a similar pulley 24 aflixed to the spindle 19.

from the foregoing, it will be seen that if the fan 18 be set in motion and water vallowed to pass through the apertures 2,

from the .chamber already described to the interior of the container 1, the water will run down over the pipes 15, and the air from the room will be meanwhile either drawn or forced through the-said container( the water passing out through the pipe 10 from the lower side of the container: that the relatively warm air of the rooin thls drawn or forced through the saidcontainer, due to the cooling effect of the water and the relatively large surface presented by the pipes 15. will be reduced in temperature and most of the impurities in the air will. pass out with the water through the pipe 10, the -unction of the screen 13 being to arrest the floating impure atoms in the air 19 is revolubly supported within a bearing:

which are of considerable size, as the air passes through the screen. As above indicated, the fan-which I have shown at 18 may operate either to force the air through thecontainer or to draw'the air through it.

In Fig. 5 the container andallv other portions of the device are the saine' as already described, but, instead of the longitudinally disposed pipes, 15 metallic rings such as indicated at 25 may be used and held in spaced relation to each other by any suitable means such as screens indicated at 26. The function of thepipes is, of course, `to present as large a cooling surface as possible, however they may be arranged, and it is obvious that a relatively large cooling surface could be obtained by the use of coarse gravel and thelike.

While I have shown and described a particular form of embodiment of my invention, I am aware that many changes therein will readily suggest themselves to others skilled in the art without departing from the spirit andfscope of my invention, and I therefore desire to avoid being limited to the exact form shown and described excel as limited the appended claim.

aving fully described my invention,

- what I claim as new and desire to protect by Letters Patent is In a device of the classdescribed, the com- 1 bination with a cylindrical container having inlet and outlet tubes' and a-l` chamber at its upper surface which communicates with the inlet tube, of apertures in the said container which communicate with the said chamber, a plurality vof pipes Within the GLEN OBRIEN.
